It is a sleep-inducing hormone that represents a very popular remedy for insomnia. It may adjust the biological response to light and darkness, being a part of the body’s natural sleep cycle. At night, more melatonin is secreted and during the day the hormone secretion decreases. The body produces melatonin by using a neurotransmitter derived from tryptophan, a well-known component under the name of serotonin.

Melatonin Functions & Benefits

Melatonin is a powerful antioxidant with anti-inflammatory properties that works by crossing the blood brain barrier and also the cell membranes. The role of these biological membranes is to regulate the transfer of substances in and out of the cell’s body and also to protect the cell. Due to its antioxidant activity, it may protect cells from the damage caused by free radicals. Therefore, it may offer protection against the aging processes, Alzheimer, and Parkinson disorders, and also it may prevent cataract occurrence.

It may be used to control the body’s internal clock. It regulates sleep and waking cycles and may help in certain neurodegenerative or sleep disorders. It is mainly used to induce sleep, representing a real help for people with insomnia. Great effectiveness is also reported from people that are working in shifts or travelling across parts of the world where the time is different or for those that are suffering from other circadian rhythm diseases. It may be used to improve the delayed sleep phase syndrome.

When taken before bedtime, supplements that contain melatonin have a good degree of success in making sleep easier and longer for children that are suffering from developmental imbalances and attention-deficit hyperactivity disorder. In case of children that are suffering from epilepsy, it has been revealed that it may minimize the occurrences and length of seizures.  Although it helps children with ADHD to fall-asleep easier, melatonin does not help in treating the symptoms of this disease. It has been suggested with the same benefits in case of children with central nervous system health conditions, such as: mental retardation, cerebral palsy, visual impairment, and autism.

Melatonin has a significant variety of other health benefits. Apart from its effectiveness regarding regulating 24-hour biological cycle, it may be recommended for anxiety, thyroid diseases, menopause, irritable bowel syndrome, certain types of cancer, and inflammatory diseases. Melatonin may prevent kidney damage by soothing the inflammation and minimizing the oxidative stress levels of the organ. Also due to its anti-inflammatory effect, it may be helpful for older people to protect the liver.  A few studies have been made on animals and it has been reported that melatonin may prevent lung inflammation on animals that are lacking sleep. It also may help in regulating serotonin levels for patients with chronic fatigue syndrome and fibromyalgia. Unfortunately, the available research is inconsistent and melatonin has received either positive or neutral feedback from users. Positive testimonials are claiming that it may improve the quality and quantity of sleep.

Many of these claims have not been fully documented by scientific studies and further research is needed in order to validate them. Even if many countries are offering this without any prescription, it is best to consult a healthcare specialist before using it to treat any condition you might have.
